The Heating Efficiency of Hot Jupiters from a Data-driven Perspective

The Astronomical Journal
The inflated radii of hot Jupiters have been explored by various theoretical mechanisms. By connecting planetary thermal evolution models with the observed properties of hot Jupiters using hierarchical Bayesian models, a theoretical parameter called the ...

Tidal locking as a negative feedback on Earth-like planetary dynamos: Consequences for magnetic shielding and habitability

Astronomy & Astrophysics
We investigate how tidal locking affects the magnetic field generation and magnetospheric protection of Earth-like planets orbiting the habitable zone of M dwarfs. While the role of stellar activity has been widely studied, the impact of tidal locking on

Extending carbon chemistry at high-pressure by synthesis of CaC2 and Ca3C7 with deprotonated polyacene- and para-poly(indenoindene)-like nanoribbons

Nature Communications
Metal carbides are known to contain small carbon units similar to those found in the molecules of methane, acetylene, and allene. However, for numerous binary systems ab initio calculations predict the formation of unusual metal carbides with exotic ...

The Effects of Radially Varying Diffusivities on Stellar Convection Zone Dynamics

The Astrophysical Journal
Convection is ubiquitous in stellar and planetary interiors, where it likely plays an integral role in the generation of magnetic fields. As the interiors of these objects remain hidden from direct observation, numerical models of convection are an ...
